Bulk Material

Chalk & Fillers

Fillers such as chalk and kaolin add volume and reduce material costs. Where several components come together, blending & homogenizing ensures uniform distribution.

  • Uniform distribution of fillers
  • Large capacities with PW PanelLine
  • Dependable discharge

Bulk Material

Flour, Sugar, Starch & More

Flour, sugar, starch, glucose, cocoa, and proteins must be stored so that their quality, taste, and functionality are preserved. Aluminum and stainless steel keep coatings out of contact with your product.

  • Custom-engineered storage and blending silos
  • No coating-related product contamination
  • Food-grade materials with excellent cleanability

Bulk Material

Recycled Plastics

Recycled plastic materials present unique challenges in storage and processing. Deodorizing silos help reduce unwanted odors, while blending silos ensure consistent material quality for efficient recycling operations.

  • Effective odor reduction and material homogenization
  • Custom PW discharge systems for consistent, reliable material flow
  • Engineered to minimize material bridging and flow disruptions

Material

Aluminum Silos

Aluminum silos resist corrosion and maintain their integrity even during long-term storage. In plastics recycling, aluminum is our primary material – including for deodorizing silos.

  • No internal coating required
  • Lightweight construction
  • Recycling rate well above 90%
Learn More

Material

Stainless Steel Silos

Stainless steel silos combine corrosion resistance with excellent hygiene – the preferred choice in food processing and other industries with high quality standards.

  • No internal coating required
  • Pickled and passivated surfaces
  • Preferred for food processing

Industry

Plastics Industry

Pellets, powder modifiers, chalk, fillers, titanium dioxide, and recycled materials: how you store them determines their quality and functionality. Our silos fit into your production layout and ensure a smooth material flow.

  • Fits into your production layout
  • Smooth flow from storage to the machine
  • Mobile containers for bag emptying

Industry

Food Industry

Flour, sugar, starch, glucose, cocoa, and proteins require storage conditions that protect quality, taste, and functionality. That is why we build food silos only in aluminum and stainless steel – with no coating that could detach.

  • No coating in contact with the product
  • Hygienic filters and flat roofs
  • Gentle discharge of sensitive ingredients
Learn More

Industry

Logistics

In bulk logistics, short loading times and smooth material flow make the difference. Loading silos enable fast, safe truck loading – planned and installed as a turnkey solution.

  • Loading silos on steel or concrete structures
  • Loading accuracy of approx. 1%
  • Turnkey from planning to installation
